IB Biology B1.1 Pub Quiz: Carbohydrates and lipids

B1.1 as a pub quiz for your class: review rounds on this subtopic, mixed with pure-fun rounds so it feels like a night out and not another test. Opens at SL; switch to HL in the builder to add the higher level cards.

What it covers

IB Biology at SL, with HL cards when you switch the level: B1.1 Carbohydrates and lipids.

The running order

nine rounds and a handout of riddles. Review rounds are drawn from this topic each time you open the quiz, so two classes never get the same paper, and every review round can be redrawn in a click.

  1. Riddle me this review
    Course terms as riddles: "I have a head that loves water and two tails that hate it…" Teams write what it is.
  2. Close-up fun
    A tiny zoomed-in patch. What's the full picture?
  3. Fact or fiction fun
    Myths and true-but-weird facts. Teams write Fact or Fiction.
  4. Think it through review
    Scenarios, odd ones out, true or false and why, puzzles: questions to reason through. Give teams a little longer.
  5. Films in science-speak fun
    A film plot, described like a research abstract. Name the film.
  6. Who am I? Scientists fun
    Three clues, hardest first. 3 points after clue 1, 2 after clue 2, 1 after clue 3.
  7. Missing vowels: course terms review
    Your key terms with the vowels taken out.
  8. Funny animal noises fun
    YouTube clips of animals making ridiculous noises. Screen off, listen, guess, then watch the reveal.
  9. Closest wins fun
    Estimation questions. Nearest team wins the point. Doubles as the tiebreaker.

A taste of the questions

Think it through

Scenarios, odd ones out and true or false and why, from IB Biology.

  1. I'm the atom at the heart of every sugar, fat, protein and strand of DNA, building chains, branches and rings. What about my bonding makes that possible?
  2. An unbranched starch chain of 100 glucose units is digested to glucose. How many water molecules does that use up?
  3. Your blood carries glucose to your cells, never starch. Which property of glucose makes it easy to transport?
  4. True or false: your liver stores glucose as glycogen because glycogen dissolves easily in the cytoplasm.
  5. Glycogen is even more branched than amylopectin. Why does heavy branching suit an animal's energy store?
  6. Starch, glycogen, amylopectin, cellulose: which is the odd one out, and why?
Answers
  1. Four covalent bonds per atom (to other carbons and to other atoms, in any arrangement)
  2. 99 (hydrolysis adds one water to split each of the 99 glycosidic bonds)
  3. It is soluble (small and polar, so it dissolves in blood plasma)
  4. False (glycogen is insoluble and compact: that is what makes it a good store)
  5. Faster glucose release (more chain ends, so more enzymes can remove glucose at once)
  6. Cellulose (beta-glucose in straight chains, for structure; the others are alpha-glucose energy stores)

Riddle me this

Course terms as riddles. Teams write what it is.

  1. I join two small molecules into one, and leave a drop of water behind every time. What am I?
  2. Add a molecule of water and I split a big molecule into its building blocks. Your gut does me all day. What am I?
  3. I'm the bushiest sugar store in your liver and muscles, branched so often that enzymes can strip me fast. What am I?
  4. I'm glucose too, but every other link of mine is flipped. My straight chains bundle into fibres that hold a plant upright. What am I?
  5. I'm a sugary flag flown on the surface of your red blood cells. Receive blood flying the wrong flag and your body attacks it. What am I?
Answers
  1. Condensation
  2. Hydrolysis
  3. Glycogen
  4. Cellulose
  5. ABO antigen

Quickfire

Short recall from the same topics.

  1. Element that can form four covalent bonds
  2. Shared pair of electrons between two atoms
  3. Linking of monomers that releases water
Answers
  1. Carbon
  2. Covalent bond
  3. Condensation

How it runs

  1. Open it in the builder. The running order loads ready to go. Swap, add or drop rounds, or draw a round's questions again.
  2. Present it or print it. Present puts each round on the projector in 16:9 with quizmaster notes. Print gives the script, team answer sheets, a picture sheet and a tally sheet on A4 or US Letter, with no projector needed.
  3. Score it. Teams swap sheets, mark, and each plays one joker to double a round. The scores page reveals the leaderboard from last place up.
